Environmental

TerraTex® environmental nonwoven geotextiles are designed to perform four primary functions: filtration, separation, in-plane drainage, and protection/cushioning.

TerraTex® environmental nonwoven geotextiles are made up of polypropylene fibers. These fibers are needled to form a stable and durable network such that the fibers retain their relative position. It is non-biodegradable and resistant to most soil chemicals, acids, and alkali with a pH range of 3 to 12. Unless noted otherwise, all values are minimum average roll values (MARV).
